The dark brown spots seem to be a bit of that mixture of earth and wood chips that cover the ground in the terrarium, for this particular snake refuses to eat anywhere BUT inside the terrarium - where they ought NOT to be fed, but what can we do? It'd have starved to death had we insisted on feeding him outside the terrarium. And in its throat you can see the very last of the mouse's tail, just the tip.

AND, of course, you can see where the snake is extra fat just now ... behind his head. That's where the mouse is.

Sabine gave me clear instructions on how to feed them, i.e. to take one of the two out of the terrarium and into the transport box to feed him there, and to feed Mr La-dee-da (who only ever eats inside the terrarium, which he SHOULD not do!) where he would eat.

Sure enough, at first I mixed up the two, but soon noticed that it must have been Mr La-dee-da in the transport box because he would simply not touch the mouse there. (He greedily !!! ate in the terrarium, and "burped", as you can see )
